A. cockerelti is distinctively marked with yellow metasomal bands that are usually interrupted and reddish tegulae. The males can be distinguished by the combination of an inconspicuous yellowish setal brush (fig. 67) on sternum IV and the shape of sternum VI (fig. 62). The latter has no significant development of lateral lobes, and the median lobe is about as long as broad with the apex emarginate. The females are often confused with A. jocosum, since both species have a black clypeus contrasted with yellow mandibles. The dentation of the female mandible (figs. 97, 98) provides a reliable criterion for separating these two species. The species is found mostly in the Mojave and Colorado deserts and is apparently a strictly vernal species. It has associated with numerous plant species in at least seven different families. Records are based on 63 males and 56 females.
